Another component is random access memory (RAM), which temporarily stores information that the CHIP uses while the computer is on.
The information stored in RAM is erased when the computer is turned off. Almost every other part of your computer connects to the system unit using cables. The cables plug into specific ports(openings), typically on the back of the system unit. Hardware that is not part of the system unit is sometimes called peripheral device or device. 2.
